Sacked Pamapuria Primary School principal Stephen Hovell claims he has been made a scapegoat for James Parker, the former deputy principal who is in prison after admitting 49 sex offences involving about 15 boys at the school.
Mr Hovell said after his dismissal last week that he intended seeking an Employment Relations Authority order reinstating him to the job he had held since 1989.
His lawyer, Bryce Quarrie, of Kaitaia, said: "The evil person, the culpable person, in all of this always has been James Parker."
The Ministry of Education replaced the school board of trustees with Commissioner Larry Forbes after the paedophile scandal engulfed the school following Parker's arrest in July last year. Mr Forbes suspended Mr Hovell the following month.
Last week, when asked about the reasons for Mr Hovell's dismissal, Mr Forbes said: "Given that there is likely to be a challenge to the decision I can't respond with specifics at the moment."
